Hello Hive account@katerinaramm,

Thanks to Hive account@eikejanssen for the mention. I can help you with your questions and make some corrections to your message:

1. Question
   Yes, all the mentioned frontends are currently working as I tested them just now. You can post any link you want there. Anyone can define a bounty on any post or comment they like, and you can even increase the bounty value of other bounties.

2. Question
   As Hive is public to the whole world, we want everyone in any timezone to be able to use our tool. Therefore, we have defined that if you want to use our tool, you need to enter the UTC time. If you need help converting time zones, there are several converters available. For example, you can use this one: https://savvytime.com/converter/utc-to-cet. We may change this in the near future if we find a better solution.

3. Question
   Yes, your posts count too. Sadly, bot comments also count, but we are planning to implement a blacklist very soon.

4. Question
   In case anything should go wrong, we will make sure that every single HIVE or HBD reaches its intended destination. However, please note that once a bounty has been started, it is saved on the blockchain and cannot be canceled on your side.

If you have any more questions, please don't hesitate to mention Hive account@hive-bounty or read our tutorial here: @hive-bounty/introducing-hive-bounty-20.

Best regards,
